i went with the 9800GT for the single slot. also note that nearly every 9800GT except the original EVGA ones are green editions, meaning they use less power and dont even need a PCI-E power connector to run. mine runs off the mb power like the old school PCI/AGP cards did.

Wow, that is a champ reply. I was going to have to use a molex to 6pin connector to hook it up. Gonna be nice just plugging it into the board and not worrying about it. So basically most are the same right? I am looking at them again on Newegg and just making sure it is a single slot and no more. Its gonna be a tight fit like I said before.

i have an old Nvidia 7300 gt, is this card compatible? otherwise, which card do i need?

8000 series or higher, and you probably don't want to get less than 64 shaders if you want to put PhysX effects to maximum. Some of the 9600s and most, if not all, GT 240s don't need PCI-e power plugs, which is nice.

well, there is a catch.

yes all green editions are single slot and require no extra power, however they all come with strange coolers and some are taller than others.

for example the Gigabyte versions, ECS and i think Gainward all have coolers pre-installed that make them take up more room than a single slot. the ECS comes with an Arctic Cooling cooler that makes it full dual slot. i know this coz i have one, bought it first and realised too late.

the Inno3D one i have is straight up single slot which is why i bought it, so might wanna make sure of that first if the size is definitly an issue.
